Les données ne sont pas ajoutées à la table mysql mais les données sont-elles en écho?

Question

J'ai un login/inscrire et voici le code de registre:

<div id="signup"> 
     <h1>Sign Up for Free</h1> 

     <form action="index.php" method="post" autocomplete="off"> 

     <div class="top-row"> 
     <div class="field-wrap"> 
      <label> 
      First Name<span class="req">*</span> 
      </label> 
      <input type="text" required autocomplete="off" name='FirstName' /> 
     </div> 

     <div class="field-wrap"> 
      <label> 
      Last Name<span class="req">*</span> 
      </label> 
      <input type="text"required autocomplete="off" name='LastName' /> 
     </div> 
     </div> 

     <div class="field-wrap"> 
     <label> 
      Username<span class="req">*</span> 
     </label> 
     <input type="text"required autocomplete="off" name='nickname' /> 
     </div> 

     <div class="field-wrap"> 
     <label> 
      Email Address<span class="req">*</span> 
     </label> 
     <input type="email"required autocomplete="off" name='Email' /> 
     </div> 

     <div class="field-wrap"> 
     <label> 
      Set A Password<span class="req">*</span> 
     </label> 
     <input type="password"required autocomplete="off" name='password'/> 
     </div> 

     <div class="field-wrap"> 
     <label class="custom-control custom-radio"> 
      <input id="PUBLIC" name="account_type" value="PUBLIC" type="radio" class="custom-control-input"> 
      <span class="custom-control-indicator" style="pointer-events: all;"></span> 
      <span class="custom-control-description">Public</span> 
     </label> 
     <label class="custom-control custom-radio"> 
      <input id="PRIVATE" name="account_type" value="PRIVATE" type="radio" class="custom-control-input"> 
      <span class="custom-control-indicator" style="pointer-events: all;"></span> 
      <span class="custom-control-description">Private</span> 
     </label> 
     </div> 


     <button type="submit" class="button button-block" name="register" />Register</button> 





     </form> 

    </div> 

    </div><!-- tab-content --> 

</div> <!-- /form --> 

Et cela est lié à la page de registre php qui semble récupérer les utilisateurs des données bien:

<?php 
/* Registration process, inserts user info into the database 
and sends account confirmation email message 
*/ 
require 'db.php'; 

global $mysqli; 

// Set session variables to be used on profile.php page 
$_SESSION['Email'] = $_POST['Email']; 
$_SESSION['FirstName'] = $_POST['FirstName']; 
$_SESSION['LastName'] = $_POST['LastName']; 



// Escape all $_POST variables to protect against SQL injections 
$first_name = $mysqli->escape_string($_POST['FirstName']); 
$last_name = $mysqli->escape_string($_POST['LastName']); 
$nickname = $mysqli->escape_string($_POST['nickname']); 
$email = $mysqli->escape_string($_POST['Email']); 
$password = $mysqli->escape_string(password_hash($_POST['password'],    PASSWORD_BCRYPT)); 
$hash = $mysqli->escape_string(md5(rand(0,1000))); 
$account_type = $mysqli->escape_string($_POST['account_type']); 


    // Check if user with that email already exists 
$result = $mysqli->query("SELECT * FROM logins WHERE email='$email'") or die($mysqli->error()); 

// We know user email exists if the rows returned are more than 0 
if ($result->num_rows > 0) { 

$_SESSION['message'] = 'User with this email already exists!'; 
header("location: error.php"); 

} 
else { // Email doesn't already exist in a database, proceed... 

// active is 0 by DEFAULT (no need to include it here) 
$sql = "INSERT INTO logins (first_name, last_name, nickname, email, password, hash, account_type) " 
     . "VALUES ('$first_name','$last_name', '$nickname', '$email','$password', '$hash', '$account_type')"; 

// Add user to the database 
if ($mysqli->query($sql)){ 

    $_SESSION['active'] = 0; //0 until user activates their account with verify.php 
    $_SESSION['logged_in'] = true; // So we know the user has logged in 
    $_SESSION['message'] = 

      "Confirmation link has been sent to $email, please verify 
      your account by clicking on the link in the message!"; 

    // Send registration confirmation link (verify.php) 
    $to  = $email; 
    $subject = 'Account Verification (Reps&Steps)'; 
    $message_body = ' 
    Hello '.$first_name.', 

    Thank you for signing up! 

    Please click this link to activate your account: 

    http://repsandsteps/login-system/verify.php?email='.$email.'&hash='.$hash; 

    mail($to, $subject, $message_body); 

    header("location: profile.php"); 

} 

    else { 
     $_SESSION['message'] = 'Registration failed!'; 
     header("location: error.php"); 
    } 

} 

Mais il ne semble pas l'ajouter dans ma base de données, j'ai vérifié qu'il peut se connecter et il peut également faire écho à la valeur qui ont été insérés dans le formulaire, mais il ne les ajoutera pas à la table et il n'y a pas semblent être des messages d'erreur provenant de la base de données ou du code, le seul message d'erreur que je reçois est celui que j'ai créé lorsque l'enregistrement échoue.

Ce sont les champs de la table:

unique_id | FirstName | LastName | nickname | Email | password | hash | account_type | active 

Answer 1

changement first_name et last_name-FirstName et LastName car utilise votre domaine dans le tableau FirstName et LastName

$sql = "INSERT INTO logins (FirstName, LastName, nickname, Email, password, hash, account_type) " 
     . "VALUES ('$first_name','$last_name', '$nickname', '$email','$password', '$hash', '$account_type')"; 

aussi le Email
